In the body, reactants and products are primarily moved around through the circulatory system, where blood serves as the transport medium. Oxygen and nutrients are delivered to cells via arteries, while waste products, such as carbon dioxide, are carried away through veins. Additionally, the lymphatic system plays a role in transporting fats and immune cells. Cellular membranes also facilitate the movement of substances in and out of cells through processes like diffusion and active transport.
The reactants for cellular respiration, glucose and oxygen, come from the food we eat and the air we breathe. Once products like ATP, carbon dioxide, and water are produced, they are used as energy sources for various cellular processes or expelled from the body through exhalation.
Messages from the endocrine system move around the body via the circulatory system.

A cell obtains reactants for respiration, such as oxygen and glucose, from the bloodstream via diffusion or active transport. Waste products, like carbon dioxide and water, are expelled from the cell and transported back to the bloodstream to be carried away and eventually excreted from the body.
The human body obtains reactants for cellular respiration through the digestion of food. Carbohydrates, fats, and proteins from the food we eat are broken down during digestion into glucose, fatty acids, and amino acids, which are then used as reactants in cellular respiration to produce energy in the form of ATP.
Nutrients, oxygen, and waste products are all moved around the body in the blood. Nutrients are transported from the digestive system to cells, oxygen is carried from the lungs to tissues, and waste products are transported to organs for elimination.

Oxygen is typically carried by the red blood cells of most animals. However, the Sea Star has no "blood" and instead uses sea water to transport its nutrients. Salt water transports the oxygen around a sea star's body.

Lean Body products are sold and manufactured by lean manufacturing or labrada nutrition.online sites offer different sales around these products and one can order them online easily.
they are tiny blood vessels around the body that connect arteries to veins. they transport oxygen,nutrients etc around the body and collect waste products
